Yorito is the main protagonist of Sola. He enjoys taking photographs of the sky and will go out of his way to do so. He meets Matsuri Shihō early on in the story and finds out she is not human and is being chased by a man —Takeshi Tsujido— who intends to kill her. Yorito tries to protect her by asking her to stay at his house. Yorito has an older sister named Aono who at the beginning of the story is in the hospital. Yorito visits her with Mana everyday and he brings her a new doll from a strange store that sells oddly designed dolls.

Yorito is in fact a paper construct made by Aono, implanted with the memories of and designed after the image of the original Yorito, who died in the past.
